FOLDING: BOX.

Specification of Letters Patent.

Patented July 27, 1915.

Application filed January 9, 1914. Serial No. 811,228.

To all whom it may concern:

Be it known that I, GEORGE C. CORNELL, a citizen of the United States, and a resident of Canton, in the county of Bradford and State of Pennsylvania, have invented certain new and useful Improvements in Folding Boxes, of which the following is a specification, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to certain improvements in collapsible boxes which can be compactly folded for shipment and includes certain fasteners by means of which the box is held in proper shape, and by means of which the lid may be readily secured.

The primary object of my invention is to provide a made-up box which can be shipped in a flat and folded condition in such a manner that the box may be instantly set up and secured.

Another object is to provide a folding box made from a single scored blank which can be set up with ease, accuracy and despatch, to provide a dust and vermin proof box.

With these and other objects in View, the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and finallV pointed out in the appended claims, it being further understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

In the accompanying drawings forming a part of this specification and in which like numerals of reference indicate similar parts in the several views: Figure 1 shows a perspective view of a folding box constructed according to my invention, disclosing the top and front flap as unfolded. Fig. 2 is a longitudinal sectional view in the direction of the arrow 2, shown in Fig. 1, disclosing the box top as closed. Fig. 3 is a section on line 3, 3, of Fig. 2. Fig. 4 shows a plan view of a scored blank. Fig. 5 shows a plan view of a modification disclosing a throw-away lunch box, and its fastening means. Fig. 6 is a lengthwise sectional view on line 6, 6 in the direction of the arrow, shown in Fig. 5. Fig. 7 is a bottom view with parts broken away of the throw-away lunch box. Fig. 8 shows an enlarged perspective detail of a securing car.

In my present invention I provide a scored blank made from paper, box board, or any other suitable material, which can be instantly set up to provide a box suitable for storing purposes, parcels post service, suit boxes, lunch boxes or any other transit or storing services.

In Fig. 4, I have shown a plan view of a one piece blank used in making a suit or similar box. The rectangular bottom section 1 ends on the score lines a, a, which run parallel and the score lines 2') and c which also run parallel and at right angles to the score lines (1 The front wall 2 of the box is encompassed by the score lines a, a, and 5, while formed opposite the front wall 2 is the rear wall 5, and continued from this rear wall 5 is the top 6 from which extends the front flap 7. As shown the score lines a, a, extend entirely across the members 1, 2, 5, 6 and 7. The score line 0, separates the back Wall 5 from the bottom 1, while the score line it, separates the top 6 from the back wall 5, the score line 1, separating the front flap 7 from the top 6. The front wall 2 is provided with the four diagonally folded corner sections or triangular folds 8, 9, 10 and 11, these folds being marked by means of the score lines (Z and e.

Forming a part of the bottom 1 are the end walls 3 and 4 formed integral with the corner sections. The rear wall 5 of the box has the triangular folds 15 and 17 and 16 and 17, formed by the scores f and g, The top 6 is provided with the end flaps 18' and 18, and these end flaps end respectively in the under-folds 19 and 19. The front flap 7 ends in the reinforcing end sections 20 and 20. As shown in Fig. 1- these reinforcing end flaps 20 and 20 are of a length equal to the width of the bottom 1 and top 6, while the end flaps 18 and 18 are also of a width equal to the bottom 1 and top 6, and also strengthening and reinforcing the ends of the box.

As shown in Fig. 4C, the end flaps 18 and 18 are separated from the triangular folds 17 and 17 by means of the cuts a, while the end flaps 18 and 18 at the opposite side are separated from the reinforcing end sections 20 and 20 by means of the cuts to, w. The score lines o, marking the outer ends of the end flaps 1 ,8 and 18' are in alinement with the ends of the end walls 3 and 4 and the connected folds.

As shown the front wall 2 at suitable points is provided with the lengthwise extending slots 2, while the front flap 7 has the locking tabs 3 having the straight shoul ders which are arranged to lock Within the slots 2. It is of course understood that these locking tabs 3 are in proper alinement with the slots 2.

In forming the box, the corner sections 8 and 9, and and 11 are folded upon one another, the inner faces of the sections 8 and 11 being brought against the inner face of the front Wall 2. This then brings the outer faces of the members 8 and 9 and 10 and 11 against one another. In this folded condition the members 8 and 9, and 10 and 11 are stapled against the front wall 2 by means of the staples f, as will be understood in referring to Fig. 1. Similarly the inner faces of the members 17 and17 are brought against the inner face of the rear wall 5, which brings the outer faces of the members 15 and 17, and 16 and 17 together.

These folded corner members are then stapled against the rear wall 5, in the manner shown in Fig. 1.

In closing the box the locking tabs 3 are secured within the slots 2. The end sections 20 and 20 are then folded against the ends 3 and 4, the end flaps 18 and 18 being foldedover the end sections 20 and 20, the under folds 19. and 19 finally being securely fastened by meansof a suitable metal clip 30, which extend through the openings 21 shown in Fig. 1, each clip having an end 31 with clenching teeth 32 whichare driven through the bottom 1, as shown in Figs. 2, 4 and 13.

From the foregoing it will be seen that the box at each corner has a two ply reinforcement, while in its completed condition the box has two three ply end walls, thus offering a box capable or withstanding hard usage, and more than ordinary crushing strains, upon the top and bottom. 7

In orderfto ship this box in a folded conditionI provide the end walls 3 and 4 with the obliquely running score grooves 70, which extend at right angles to the score grooves 7, g and d and 6. This construction permits the end walls 3 and 4 being shoved outward so that the walls will bend on the score lines 70, permitting the front and rear walls to fold upon the inner face of the bottom 1, as indicated in Fig. 13, in which condition the box can be folded flat for shipping purposes. I

In using this box it is of course understood that all that is necessary to do is to carry the end walls 3 and 4 toward one another. The tendency of the score end walls 3 and 4 is to bulge outward, but the sections 18 and 18 and 20 and 20 form a double reinforcement preventing this outward bulging tendency and counter-acting the same whenthe box is in a set up condition. In exercising care in removing the locking tabs a bax constructed as above can be repeatedly use In Figs. 5, 6 and 7, I show a modification which covers my invention where my construction methods are embraced in a cheap, lunch box. In this modification as shown in Fig. 5, the triangular corner folds are loosely held to the end walls and no staples are used to hold the folds in place. As shown this modification comprises the bottom 35, the front wall 36, the rear wall 37, the end walls 38 and 39, the top 44 and the flap 45.

The front wall 36 has the triangular corner folds 40 and 41 which are folded upon one another while at the opposite ends are the triangular folds 40 and 41, which are also folded upon one another in such a manner that these folded members will lie against the end wall 38 and 39. The rear wall 37 is provided with a triangular foldable corner section comprising the folds 42, 43 and 42 and 43. The top 44 has the flaps 46 and 46 and the under folds 47 and 47, while the front flap has the end flaps 48 and 48' adapted to fold against the ends 38 and 39 of the box in its folded condition.

As shown in Figs. 7 and 8, the under folds 47 are each provided with an ear 49 and 49 forming an integral part of the under folds 47 and 47 and these ears are held in position by means of staples 50 secured intermediate of theends of the ears. Below one ear is secured the knotted end of a string 52 and this string in the closed condition of the box at the opposite end is wound about the opposite ear 49, as shown in Fig. 7, to properly hold the top.

While this box can be repeatedly used it can be so cheaply made that the same can be used as a throw-away lunch box.

As shown in Figs. 1 and 5, the triangular corner sections are capable of being folded either against the end or front and back walls. The obliquely running score grooves H enter from the corners of the blank.

Where these foldable boxes are employed in shipping eggs, I prefer using the ordinary filler together with a false top and bottom, the top and bottom being made of corrugated straw board with the ends bent at right angles to help strengthen the ends of the box.

It is of course understood that boxes embodying my invention may be made in various sizes and of any suitable material.

7 My box is simple and inexpensive to construction, and both durable and efficient in operation. The boxes further can be shipped in a folded condition in such a man- 1,148,219 Ital;

her that they can be set up with ease, accuracy and despatch.
